Unless I'm mistaken, only the usrp sink/source blocks report overflow
(source) or underflow (sink). You can see this mentioned in
uhd/docs/general.dox (uhd github repo).
Did you listen to the warnings you get on startup about changing buffer
sizes with a series of commands requiring sudo? That helped me resolve some
overflow, otherwise it sounds like you'll need to drop your sample rate
unless you need it as high as it currently is.
